I have "Whistling Coon," on two diamond disks. The DD # is 50478-L. The sketch was recorded by Edward Meeker and the Empire vaudeville Company. This is one of the most blatantly racist "coon" records ever released. I've played it for people, but I asked them to take the sketch for what it is, a historical artifact, and not get mad at the record, or me. The flip side on Diamond Disks (50478-R,) was "The Colored Recruits." That sketch was recorded by Golden and Heins (with Band). Both selections were WW 1-based minstrel sketches. I doubt seriously that they were ever released as Royal Purples. Randy Minor
